The Regulan system, a star system situated in the Outer Rim Territories' Albanin sector, was in proximity to Dubrava and Barab I. This system contained the planets Blaudu Octus and Blaudu Sextus, the latter being the site of an uprising that took place during 44 ABY.
According to Jason Fry, the reference to the "Blaudu Sextus system" within the Essential Atlas Online Companion (situated in the Prefsbelt sector) was erroneous. The appendix correctly identifies Blaudu Sextus as being part of the Regulan system.
